UNITED STATES BBYAN P. JOYCE. F DAVENPORT, IOWA, LBSIGOB Application llea September [GRANTED UDB). 'KHE GT 0F The present invention relates to Huid separating means. 4

The primary object of my'invcntion is the provision .of means for separating one l luidfrom another.

Another object is the provision of means which while normally acting ato separate oneiluid from anotherV in acvlinder will automaticall accommodate itselfto ch lo oi resure in the fluids in4 said cylinder.

ith the foregoingandgother objects in view, my invention resides in the novel ar-frangement and combination of parts and.

in the ldetails of 4.construction 'liereinaiter' l5 described arid claimed, it bcin'g'I understood j 'that changes-in the precise embodiment of the-invention lieijeindisclosed may be madeV4 within the scope of what is claimed without.'

I Ahave shown yat 5 a cylinder provided I0 with the usual packing 6. Reciprocally mounted in this cylinder isapistonorplun of; ge arating ri "g-tlfat" or the spigil spring 14 any resilient In the preferred embodiment of my invention the cylinder is -formed with an olf;

)t set as at 8 to provide a pair ofchambers 9 and 10 filled with dilerent uids. Sur-v rounding the pi'ston 7 and seated against theinner walls of the chamber@ is the separatin ri 11 for preventing intermix- 0 ture o? the nids in the two chambers. At-

tached to-this ring 11 as by .means of screws 12 is a acking 13 which surrounds the iston an aids the ring in maintaining the uids in their respective chambers.

In the preferred embodiment of my invention a spiral sprin 14 is interposed between the ring and t e asking' secured thereto and the offset 8 in t e cylinder. The separating ring is dished to form angularly 5 directed portions l5 and 16 seating in close contact with the inner walls of the cylinder and the outer periphery of the piston. The

spring 14 serves. to maintain the ring in sealing contact with the pisto'n and the inner walls of the c I inder and thereby noi nially prevent lea cage of the uids from one chamber to another on movement-of the piston. Should leakage occur, however, the

spring 14 enables the separating ring to ad? just itself automatically .to the chan in lrassure in the chamber 9.
